`[{:(2x+y,4x),(5x-7,4x):}]=[{:(7,7y-13),(y,x+6):}]` then the value of `x,y` is

If [2x+y4x5x-74x]=[77y-13yx+6] then the value of x+y is x=3,y=1 (b) x=2,y=3(c)x=2,y=4(d)x=3y=3

If [{:(x, 0), (0, y):}] + [{:(-y, 4),(7, x):}] = [{:(4, 4), (7, 6):}] then x = ____ and y=___.

If x:y= 3: 4, then the value of (5x - 2y)/(7x + 2y) =

If x,y,z in R & Delta =|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16 then the value of x is

If X and Y are the matrices of order 2xx2 each and 2x-3y=[{:(-7,0),(7,-13):}] and 3x+2y =[{:(9,13),(4,13):}] then what is Y equal to

If X and Y are the matrices of order 2 xx 2 each and 2X-3Y=[{:(-7,0),(7,-13):}]and 3X + 2Y=[{:(9,13),(4,13):}] , then what is Y equal to ?

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x
